Ask testnet operator to send L1 tokens and ETH to your chain address
-
Check balance of your tokens once they are transferred:
# Note: Account address should be without "0x" export ACCOUNT_ADDRESS="<account-address>" export GETH_CHAIN_ID="1212" export GETH_CHAIN_URL="https://fixturenet-eth.laconic.com" export ASSET_ADDRESS_1=$(jq -r --arg chainId "$GETH_CHAIN_ID" '.[$chainId][0].contracts.TestToken.address' assets.json) export ASSET_ADDRESS_2=$(jq -r --arg chainId "$GETH_CHAIN_ID" '.[$chainId][0].contracts.TestToken2.address' assets.json) # Check balance of eth account curl -X POST $GETH_CHAIN_URL \ -H "Content-Type: application/json" \ -d '{ "jsonrpc":"2.0", "method":"eth_getBalance", "params":["'"$ACCOUNT_ADDRESS"'", "latest"], "id":1 }' # Check balance of first asset address curl -X POST $GETH_CHAIN_URL \ -H "Content-Type: application/json" \ -d '{ "jsonrpc":"2.0", "method":"eth_call", "params":[{ "to": "'"$ASSET_ADDRESS_1"'", "data": "0x70a08231000000000000000000000000'"$ACCOUNT_ADDRESS"'" }, "latest"], "id":1 }' # Check balance of second asset address curl -X POST $GETH_CHAIN_URL \ -H "Content-Type: application/json" \ -d '{ "jsonrpc":"2.0", "method":"eth_call", "params":[{ "to": "'"$ASSET_ADDRESS_2"'", "data": "0x70a08231000000000000000000000000'"$ACCOUNT_ADDRESS"'" }, "latest"], "id":1 }'
-
Edit
nitro-vars.yml
and add the following variables:# Private key for your Nitro account (same as the one used in stage0 onboarding) # Export the key from Laconic wallet (https://wallet.laconic.com) nitro_sc_pk: "" # Private key for a funded account on L1 # This account should have L1 tokens for funding your Nitro channels nitro_chain_pk: "" # Multiaddr with publically accessible IP address / DNS for your L1 nitro node # Use port 3007 # Example: "/ip4/192.168.x.y/tcp/3007" # Example: "/dns4/example.com/tcp/3007" nitro_l1_ext_multiaddr: "" # Multiaddr with publically accessible IP address / DNS for your L2 nitro node # Use port 3009 # Example: "/ip4/192.168.x.y/tcp/3009" # Example: "/dns4/example.com/tcp/3009" nitro_l2_ext_multiaddr: ""
-
Edit the
setup-vars.yml
to update the target directory:# Set absolute path to desired deployments directory (under your user) # Example: /home/dev/nitro-node-deployments ... nitro_directory: <path-to-deployments-dir> ... # Will create deployments at <path-to-deployments-dir>/l1-nitro-deployment and <path-to-deployments-dir>/l2-nitro-deployment
Run Nitro Nodes
Nitro nodes can be set up on a target machine using Ansible:
-
In
testnet-ops/nitro-nodes-setup
, create a newhosts.ini
file:cp ../hosts.example.ini hosts.ini
-
Edit the
hosts.ini
file to run the playbook on a remote machine:[<deployment_host>] <host_name> ansible_host=<target_ip> ansible_user=<ssh_user> ansible_ssh_common_args='-o ForwardAgent=yes'
- Replace
<deployment_host>
withnitro_host
- Replace
<host_name>
with the alias of your choice - Replace
<target_ip>
with the IP address or hostname of the target machine - Replace
<ssh_user>
with the username of the user that you set up on target machine (e.g. dev, ubuntu)
- Replace
-
Verify that you are able to connect to the host using the following command
ansible all -m ping -i hosts.ini # If using password based authentication, enter the ssh password on prompt; otherwise, leave it blank # Expected output: # <host_name> | SUCCESS => { # "ansible_facts": { # "discovered_interpreter_python": "/usr/bin/python3.10" # }, # "changed": false, # "ping": "pong" # }
-
Execute the
run-nitro-nodes.yml
Ansible playbook to setup and run a Nitro node (L1+L2):LANG=en_US.utf8 ansible-playbook -i hosts.ini run-nitro-nodes.yml --extra-vars='{ "target_host": "nitro_host"}' --user $USER
Check Deployment Status
-
Run the following commands on deployment machine:
cd <path-to-deployments-dir> # Check the logs, ensure that the nodes are running laconic-so deployment --dir l1-nitro-deployment logs nitro-node -f laconic-so deployment --dir l2-nitro-deployment logs nitro-node -f # Let L1 node sync up with the chain # Expected logs after sync: # nitro-node-1 | 2:04PM INF Initializing Http RPC transport... # nitro-node-1 | 2:04PM INF Completed RPC server initialization url=127.0.0.1:4005/api/v1
-
Get your Nitro node's info:
laconic-so deployment --dir l2-nitro-deployment exec nitro-rpc-client "nitro-rpc-client get-node-info -p 4005 -h nitro-node" # Expected output: # { # "SCAddress": "0xd0eA8b27591b1D070cCcD4D30b8D408fe794FDfc", # "MessageServicePeerId": "16Uiu2HAmSHRjoxveaPmJipzmdq69U8zme8BMnFjSBPferj1E5XAd" # } # SCAddress -> nitro address, MessageServicePeerId -> libp2p peer id
Create Channels
Create a ledger channel with the bridge on L1 which is mirrored on L2
-
Run the following commands on deployment machine
-
Set required variables:
cd <path-to-deployments-dir> export BRIDGE_NITRO_ADDRESS=$(yq eval '.bridge_nitro_address' nitro-node-config.yml) export GETH_CHAIN_ID="1212" # Get asset addresses from assets.json file export ASSET_ADDRESS_1=$(jq -r --arg chainId "$GETH_CHAIN_ID" '.[$chainId][0].contracts.TestToken.address' assets.json) export ASSET_ADDRESS_2=$(jq -r --arg chainId "$GETH_CHAIN_ID" '.[$chainId][0].contracts.TestToken2.address' assets.json)
-
Check that you have no existing channels on L1 or L2:
laconic-so deployment --dir l1-nitro-deployment exec nitro-rpc-client "nitro-rpc-client get-all-ledger-channels -p 4005 -h nitro-node" laconic-so deployment --dir l2-nitro-deployment exec nitro-rpc-client "nitro-rpc-client get-all-ledger-channels -p 4005 -h nitro-node" # Expected output: # []
-
Ensure that your account has enough balance of tokens from
assets.json
-
Create a ledger channel between your L1 Nitro node and Bridge with custom asset:
laconic-so deployment --dir l1-nitro-deployment exec nitro-rpc-client "nitro-rpc-client direct-fund $BRIDGE_NITRO_ADDRESS --asset "$ASSET_ADDRESS_1:1000,1000" --asset "$ASSET_ADDRESS_2:1000,1000" -p 4005 -h nitro-node" # Follow your L1 Nitro node logs for progress # Expected Output: # Objective started DirectFunding-0x161d289a50222caa781db215bb82a3ede4f557217742245525b8e8cbff04ec21 # Channel Open 0x161d289a50222caa781db215bb82a3ede4f557217742245525b8e8cbff04ec21 # Set the resulting ledger channel id in a variable export LEDGER_CHANNEL_ID=
- Check the Troubleshooting section if command to create a ledger channel fails or gets stuck
-
Once direct-fund objective is complete, the bridge will create a mirrored channel on L2
-
Check L2 Nitro node's logs to see that a bridged-fund objective completed:
laconic-so deployment --dir l2-nitro-deployment logs nitro-node -f --tail 30 # Expected Output: # nitro-node-1 | 5:01AM INF INFO Objective cranked address=0xaaa6628ec44a8a742987ef3a114ddfe2d4f7adce objective-id=bridgedfunding-0x6a9f5ccf1fa802525d794f4a899897f947615f6acc7141e61e056a8bfca29179 waiting-for=WaitingForNothing # nitro-node-1 | 5:01AM INF INFO Objective is complete & returned to API address=0xaaa6628ec44a8a742987ef3a114ddfe2d4f7adce objective-id=bridgedfunding-0x6a9f5ccf1fa802525d794f4a899897f947615f6acc7141e61e056a8bfca29179
-
Check status of L1 ledger channel with the bridge using channel id:
laconic-so deployment --dir l1-nitro-deployment exec nitro-rpc-client "nitro-rpc-client get-ledger-channel $LEDGER_CHANNEL_ID -p 4005 -h nitro-node" # Example output: # { # ID: '0xbb28acc2e1543f4b41eb1ab9eb2e354b18554aefe4e7f0fa5f20046869d8553f', # Status: 'Open', # Balances: [ # { # AssetAddress: '0xa6b4b8b84576047a53255649b4994743d9c83a71', # Me: '0xdaaa6ef3bc03f9c7dabc9a02847387d2c19107f5', # Them: '0xf0e6a85c6d23aca9ff1b83477d426ed26f218185', # MyBalance: 1000n, # TheirBalance: 1000n # }, # { # AssetAddress: '0x0000000000000000000000000000000000000000', # Me: '0xdaaa6ef3bc03f9c7dabc9a02847387d2c19107f5', # Them: '0xf0e6a85c6d23aca9ff1b83477d426ed26f218185', # MyBalance: 1000n, # TheirBalance: 1000n # } # ], # ChannelMode: 'Open' # }
-
Check status of the mirrored channel on L2:
laconic-so deployment --dir l2-nitro-deployment exec nitro-rpc-client "nitro-rpc-client get-all-ledger-channels -p 4005 -h nitro-node" # Example output: # [ # { # "ID": "0xb34210b763d4fdd534190ba11886ad1daa1e411c87be6fd20cff74cd25077c46", # "Status": "Open", # "Balances": [ # { # "AssetAddress": "0xa4351114dae1abeb2d552d441c9733c72682a45d", # "Me": "0x075400039e303b3fb46c0cff0404c5fa61947c05", # "Them": "0xf0e6a85c6d23aca9ff1b83477d426ed26f218185", # "MyBalance": 1000, # "TheirBalance": 1000 # }, # { # "AssetAddress": "0x314e43f9825b10961859c2a62c2de6a765c1c1f1", # "Me": "0x075400039e303b3fb46c0cff0404c5fa61947c05", # "Them": "0xf0e6a85c6d23aca9ff1b83477d426ed26f218185", # "MyBalance": 1000, # "TheirBalance": 1000 # } # ], # "ChannelMode": "Open" # } # ]
Payments On L2 Channel
Perform payments using a virtual payment channel created with another Nitro node over the mirrored L2 channel with bridge as an intermediary
-
Prerequisite: Ledger channel is required to create a payment channel
-
Note: Currently payment channel is created from first asset present in ledger channel
-
Run the following commands on deployment machine
-
Switch to the
nitro-node
directory:cd <path-to-deployments-dir>
-
Check status of the mirrored channel on L2:
laconic-so deployment --dir l2-nitro-deployment exec nitro-rpc-client "nitro-rpc-client get-all-ledger-channels -p 4005 -h nitro-node" # Example output: # [ # { # "ID": "0xb34210b763d4fdd534190ba11886ad1daa1e411c87be6fd20cff74cd25077c46", # "Status": "Open", # "Balances": [ # { # "AssetAddress": "0xa4351114dae1abeb2d552d441c9733c72682a45d", # "Me": "0x075400039e303b3fb46c0cff0404c5fa61947c05", # "Them": "0xf0e6a85c6d23aca9ff1b83477d426ed26f218185", # "MyBalance": 1000, # "TheirBalance": 1000 # }, # { # "AssetAddress": "0x314e43f9825b10961859c2a62c2de6a765c1c1f1", # "Me": "0x075400039e303b3fb46c0cff0404c5fa61947c05", # "Them": "0xf0e6a85c6d23aca9ff1b83477d426ed26f218185", # "MyBalance": 1000, # "TheirBalance": 1000 # } # ], # "ChannelMode": "Open" # } # ]
-
Set required variables:
export BRIDGE_NITRO_ADDRESS=$(yq eval '.bridge_nitro_address' nitro-node-config.yml) # Mirrored channel on L2 export L2_CHANNEL_ID=<l2-channel-id> # Amount to create the payment channel with export PAYMENT_CHANNEL_AMOUNT=500
-
Set counterparty address
export COUNTER_PARTY_ADDRESS=<counterparty-nitro-address>
-
Get the nitro address of the counterparty's node with whom you want create payment channel
-
To get the nitro address of the your node:
laconic-so deployment --dir l2-nitro-deployment exec nitro-rpc-client "nitro-rpc-client get-node-info -p 4005 -h nitro-node" # `SCAddress` -> nitro address
-
-
Check for existing payment channels for the L2 channel:
laconic-so deployment --dir l2-nitro-deployment exec nitro-rpc-client "nitro-rpc-client get-payment-channels-by-ledger $L2_CHANNEL_ID -p 4005 -h nitro-node"
-
Create a virtual payment channel:
laconic-so deployment --dir l2-nitro-deployment exec nitro-rpc-client "nitro-rpc-client virtual-fund $COUNTER_PARTY_ADDRESS $BRIDGE_NITRO_ADDRESS --amount $PAYMENT_CHANNEL_AMOUNT -p 4005 -h nitro-node" # Follow your L2 Nitro node logs for progress # Expected Output: # Objective started VirtualFund-0x43db45a101658387263b36d613322cc952d8ce5b70de51e3a495513c256bef4d # Channel Open 0x43db45a101658387263b36d613322cc952d8ce5b70de51e3a495513c256bef4d # Set the resulting payment channel id in a variable PAYMENT_CHANNEL_ID=<payment-channel-id>
Multiple virtual payment channels can be created at once
-
Check the payment channel's status:
laconic-so deployment --dir l2-nitro-deployment exec nitro-rpc-client "nitro-rpc-client get-payment-channel $PAYMENT_CHANNEL_ID -p 4005 -h nitro-node" # Expected output: # { # ID: '0xb29aeb32c9495a793ebf7bd116232075d1e7bfe89fc82281c7d498e3ffd3e3bf', # Status: 'Open', # Balance: { # AssetAddress: '0x0000000000000000000000000000000000000000', # Payee: '<your-nitro-address>', # Payer: '<counterparty-nitro-address>', # PaidSoFar: 0n, # RemainingFunds: <payment-channel-amount>n # } # }
-
Send payments using the virtual payment channel:
export PAY_AMOUNT=200 laconic-so deployment --dir l2-nitro-deployment exec nitro-rpc-client "nitro-rpc-client pay $PAYMENT_CHANNEL_ID $PAY_AMOUNT -p 4005 -h nitro-node" # Expected output # { # Amount: <pay-amount>, # Channel: '<payment-channel-id>' # } # This can be done multiple times until the payment channel balance is exhausted
-
Check payment channel's status again to view updated channel state
-
Close the payment channel to settle on the L2 mirrored channel:
laconic-so deployment --dir l2-nitro-deployment exec nitro-rpc-client "nitro-rpc-client virtual-defund $PAYMENT_CHANNEL_ID -p 4005 -h nitro-node" # Expected output: # Objective started VirtualDefund-0x43db45a101658387263b36d613322cc952d8ce5b70de51e3a495513c256bef4d # Channel complete 0x43db45a101658387263b36d613322cc952d8ce5b70de51e3a495513c256bef4d
-
Check L2 mirrored channel's status after the virtual payment channel is closed:
- This can be checked by both nodes
laconic-so deployment --dir l2-nitro-deployment exec nitro-rpc-client "nitro-rpc-client get-all-ledger-channels -p 4005 -h nitro-node" # Example output: # [ # { # "ID": "0xb34210b763d4fdd534190ba11886ad1daa1e411c87be6fd20cff74cd25077c46", # "Status": "Open", # "Balances": [ # { # "AssetAddress": "0xa4351114dae1abeb2d552d441c9733c72682a45d", # "Me": "0x075400039e303b3fb46c0cff0404c5fa61947c05", # "Them": "0xf0e6a85c6d23aca9ff1b83477d426ed26f218185", # "MyBalance": <updated balance>, # "TheirBalance": <updated balance> # }, # { # "AssetAddress": "0x314e43f9825b10961859c2a62c2de6a765c1c1f1", # "Me": "0x075400039e303b3fb46c0cff0404c5fa61947c05", # "Them": "0xf0e6a85c6d23aca9ff1b83477d426ed26f218185", # "MyBalance": <updated balance>, # "TheirBalance": <updated balance> # } # ], # "ChannelMode": "Open" # } # ]
Your balance on the L2 channel should be reduced by total payments done on the virtual payment channel

Update nitro nodes
-
Switch to deployments dir:
cd $DEPLOYMENTS_DIR/nitro-node
-
Rebuild containers:
laconic-so --stack ~/cerc/nitro-stack/stack-orchestrator/stacks/nitro-node build-containers --force-rebuild
-
Restart the nodes
laconic-so deployment --dir l1-nitro-deployment stop laconic-so deployment --dir l1-nitro-deployment start laconic-so deployment --dir l2-nitro-deployment stop laconic-so deployment --dir l2-nitro-deployment start
Clean up
-
Switch to deployments dir:
cd <path-to-deployments-dir>
-
Stop all Nitro services running in the background:
laconic-so deployment --dir l1-nitro-deployment stop laconic-so deployment --dir l2-nitro-deployment stop
-
To stop all services and also delete data:
laconic-so deployment --dir l1-nitro-deployment stop --delete-volumes laconic-so deployment --dir l2-nitro-deployment stop --delete-volumes # Remove deployment directories (deployments will have to be recreated for a re-run) sudo rm -r l1-nitro-deployment sudo rm -r l2-nitro-deployment
Troubleshooting
-
Check the logs of nitro node to see if the objective is completed
# To check logs of L1 nitro-node laconic-so deployment --dir l1-nitro-deployment logs nitro-node -f --tail 30 # To check logs of L2 nitro-node laconic-so deployment --dir l2-nitro-deployment logs nitro-node -f --tail 30
- If the objective is completed, you can safely stop (
Ctrl+C
) the running CLI command and continue with the further instructions
- If the objective is completed, you can safely stop (
-
Stop (
Ctrl+C
) the direct-fund command if it is stuck -
Restart the L1 Nitro node:
-
Stop the deployment:
cd <path-to-deployments-dir> laconic-so deployment --dir l1-nitro-deployment stop
-
Reset the node's durable store:
sudo rm -rf l1-nitro-deployment/data/nitro_node_data mkdir l1-nitro-deployment/data/nitro_node_data
-
Restart the deployment:
laconic-so deployment --dir l1-nitro-deployment start
